cillizza, appreciate your time. this weekend at the state fair chuck todd in iowa spoke to some voters and they re exprszing their frustration over the clinton e-mail issue and the appeal of other candidates. take a listen. does seem to me she s hiding something. she owes you a better explanation. absolutely. we re smarter than that. it s nice to have an outsi outsider. although he s been in politics for a long time it s nice to have someone who is not a clinton or a bush. now down to rumors, gore jumping in. do you think that s about her? it s got to be. it s got to sting. former five-term iowa senator tom harkin gave his former colleague a big boost over the weekend joining clinton at the iowa state fair after endorsing her. he joins me now. senator, thank you for coming on the program. you just heard from your fellow iowans, thoughts that perhaps hillary clinton is hiding something, that her paperhaps t want new blood. you said saturday she s doing everything right
